Runway roe GLASS.

Application filed June 19, 1920. Serlal No. 350,244.

To all whom it may concern:

Be it known that 1, Homer: H. BUGGIE, a citizen of the United States ofAmerica,

residing at Toledo, in the county of Lucas dows of automobiles or othervehicles, which.

commonly employ a vertically slidable glass plate.

It is the object of the present invention to provide a runway for asliding window lass, which runway is formed of a strip 0t material thatis yielding so as to readily conform to any irregularities in thethickness of the glass, yet possesses sufiicient firmness to provide aproper runway for the glass. I

find that back check piano felt having a channel formed therein eitherduring initial process of manufacture or subsequently cut therein ishighly advantageous for this purpose, and have hence illustrated theinvention as employing such strip. The prevention of rattling of asliding vehicle window glass in any of its positions 9f adjustment is afurther object of the invention.

In the drawings:

Figure 1 is an interior view of a vehicle door having a sliding windowof the type to which the invention is applicable;

Figure 2 is a sectional detail view taken on line 2-2 of Figure 1 andshowing in cross section, the engagement of the glass with the runway;

Figure 3 is a fragmentary perspective view of the runway engaged by theglass.

In these views, the reference character A designates a vehicle doorprovided in its upper portion with a window opening B,

which opening is fitted with a vertically slidable glass plate C. Saidplate engages at its lateral edges in channels l). which are formed inthe window frame portion E of the door A. Within each of the channels D,

there is disposed a runway F, which may be advantageously formed of arectangular strip of felt, although like yieldable material could beemployed. 1 have found that, for this purpose, a very desirable materialis back check piano felt, having formed therein either during theinitial manufacture of the strip, or by subsequent cutting or machiningprocess, a groove G wherein the lateral edges of the glass C may engage.By so forming the groove in the strip F, none of the initial stifinessof the fibre is lost. A strip formed in the described manner is foundhighly advantageous, as compared with a strip which is folded to achannel form, one of its desirable effects be-- ing the establishment ofa water proof seal between the glass and its frame. It will be observedthat the thickness of material provided at the bottom of the groove G issomewhat greater than that at each side of said groove, as thisincreases the firmness of the channel and assists in maintaining itsshape.

It is found that an increased durability results from use of a runwayformed as above described and that any binding tendency between therunway and glass is substantially eliminated; Also the employment of thedescribed runway facilitates assembly, since no bending of the same isnecessary prior to insertion thereof, in the channels D, so that it maybe very readily introduced into the channels without manipulation.

Vhat I claim as my invention is:

1. A window runway comprising a strip of fibrous yieldable material,having a longitudinal channel therein-for receiving the edge of a windowglass, said channel being formed in the strip.,

2. A window runway comprising a strip of back-check-piano felt. having alongitudinal channel therein for receiving the edge of a window glass,said channel being formed in the strip.

3. A window runway comprising a strip of fibrous yieldable materialhaving a longitudinal channel therein for receiving the edge of a windowglass, the thickness of said material at the bottom of saidchannel'being greater than that at the sides of the channel, saidchannel being formed in the strip.

In testimony whereof I affix my si ature.

HORACE H. BUPrIE.
